- Attempts to retrieve a performance measurement log entry from the performance measurement log.
-
- Attempts to retrieve the performance log entry specified by LogEntryKey. If LogEntryKey is
- zero on entry, then an attempt is made to retrieve the first entry from the performance log,
- and the key for the second entry in the log is returned. If the performance log is empty,
- then no entry is retrieved and zero is returned. If LogEntryKey is not zero, then the performance
- log entry associated with LogEntryKey is retrieved, and the key for the next entry in the log is
- returned. If LogEntryKey is the key for the last entry in the log, then the last log entry is
- retrieved and an implementation specific non-zero key value that specifies the end of the performance
- log is returned. If LogEntryKey is equal this implementation specific non-zero key value, then no entry
- is retrieved and zero is returned. In the cases where a performance log entry can be returned,
- the log entry is returned in Handle, Token, Module, StartTimeStamp, and EndTimeStamp.
